Hydrocarbon recovery / LTS dew point control units

The hydrocarbon recovery from natural gas streams can be obtained with LTS dew point control units.
If sufficient pressure is available, the recovery of hydrocarbon can be accomplished by expansion refrigeration in a LTS (Low Temperature Separation) unit. This system uses the Joule-Thomson effect to reduce the gas temperature upon adiabatic expansion. To avoid hydrate formation glycol or methanol are injected, thus the process can actually accomplish dew point control of both water and hydrocarbon in a single unit.
In case no excess pressure is available, low temperature can be achieved by using mechanical refrigeration systems.
